Abstract

The invention discloses a blue-to-black disperse dye composition and a dye product. The blue-to-black disperse dye composition comprises a component A, a component B, a component C and a component D. The component A is selected from at least one of compounds shown in a formula (I), the component B is selected from at least one of compounds shown in a formula (II), the component C is selected from at least one of compounds shown in a formula (III), and the component D is selected from at least one of compounds shown in a formula (III). The component D is selected from at least one of compounds shown in a formula (IV). The invention also provides a blue-to-black disperse dye product, which comprises the blue-to-black disperse dye composition and an auxiliary agent. When the disperse dye provided by the invention is applied to dyeing of hydrophobic fiber materials, various color fastnesses are excellent, and the problems of discoloration, staining and the like of dyed fabrics in clear water and washed clothes after various polyester fabrics are dyed by the disperse dye can be effectively solved.

Description

(1) Technical field [0001] The invention relates to a blue to black disperse dye composition and dye products. (2) Background technology [0002] Among the disperse dyes, the blue-black series of dyes are used the most. The traditional dye composition is composed of C.I. Disperse Blue 291:1, C.I. Disperse Violet 93 and C.I. Disperse Orange 76, because C.I. The aromatic amines that are harmful to the human body are produced and are allergic to the human body. They have been listed as banned dyes by Germany and other EU countries; recently it was found that C.I. Disperse Violet 93 is also ecologically unsafe. [0003] The new crown epidemic has increased the public's attention to sports health, and the design of sportswear is mostly based on contrasting colors, so it also puts forward higher requirements for fastness. It is extremely urgent to find a new type of disperse blue-black series dyes that are environmentally friendly and have excellent color fastness. (3) Contents...
